Original application filed September 25, 1916, Serial No. 122,017. Divided and this application filed llanuary a, 1918. Serial No. 210,974,.

I and I do hereby declare the following to be a full, clear. and exact description of the invention, such as will enable others skilledin the art to which it appcrtains to make and use the same.

My invention relates to improvements in apparatus for agitating the contents of such vessels as tanks. vats and the like.

' One of the objects of my invention issto provide means which will more quickly, thoroughly, effectively and uniformly expose the contents of thetank to the heating or cooling clllec-t of the walls of the containing vessel. It is highly desirable to realize those results by the use of cheap and convenient devices for that purpose. I aim to provide apparatus cheap to construct and cheap and convenient to operate.

it will be obvious also that my invention may be employed for other uses and realize other results.

These and other objects of myinvention will be better understood from a description of an embodiment of the invention.

This. a 'iplication is a division of my application Serial NoflQZOlT, filed Sept. 25, 1916.

Fig. 1 is taken along the line 3-1 of Fig.

2, looking in the direction of the arrow V.

Referring now to the drawingand to the embodiment of the invention illustrated therein, at A is shown a tank or vat which is here shown as evlindrical in form. The

bottom wall id of the tank is inclined downis jacketed. as shown at wardly with respect to the ends of the Side walls. l-prcfcr to dish or incline-tho bottom of the tank downwardly, in all directions. from the juncture of the bottom with the side walls. toward the center. The tank C and supported 4 upon supporting means. such as columns D.

Agitating means. here shown as a propeller E, is mounted closely ad acent the 1uncture certain new and and is companion to my application Serial No. 189,719, filed Sept. 4, 1917.

F of the sidewalls and bottom of the tank. The propeller E is mounted upon a shaft G, which passes through the side walls of the tank near the bottom thereof. In the embodiment shown, the shaft passes through a sleeve H, which is firmly secured in the side walls of the-tank, In-the embodiment shown, threads J are employed to connect the sleeve to the tank proper.

At K is shown a pulley, through which the propeller and shaft are rotated. \Vhen the propeller is mounted near the bottom of the tank, as illustrated in the drawing effective agitation and distribution of the contents of the tank (an be realized, even though such contents aregreatly reduced, and where milk or cream are to be agitated or distributed, the apparatus can be employed, even though the contents of the tank are. greatly reduced, without churning the same into butter.

When the propeller is operated, aportion of the contents of the tank is thrown out radially, or substantially radially, in the direction of-the arrows m, m and 3 The fluid moving in the direction of the arrows a", will strike the portions of the side walls 'inthe direction of the arrows a2, toward .the opposite walls of the tank.

The fluid hurled in the direction of arrow 7 will strike the portion of'the bottom of the tank adjacent 7), and will bedeflected toward tho opposite side, in-the direction of the arrow v The device E will also drive a part of the liquid across the tank, striking the opposite side walls of the point p'andthe bottom wall inthe neighborhood of the point 0. Of. course, these parts being inclined, the liquid will be deflected. All these currents will cause a great agitation of the contents of the tank and a very thorough distribution of the liquid throughout the tank and exposure of the same to the CO0ll11 or heating effect of the walls of the tank. ipes M, N and O'are employed for supplying or withdrawing heating and cooling agencies from the jacket surrounding the tank, and a pipe v and that any convenient means may be em-- S is employed for supplying to or with- I drawing liquid from the tank itself.

.It will beunderstood that any convenient meansmay be employed for supplying or withdrawing fluids from the tank or jacket,

ployed for driving the device E. It will also be understood that many departures 'may be made from the form and details of the embodiment of my invention, Without departing from the spirit thereof.

I claim 1 1. In a device of the class described, the combination of a tank pfovided with side walls and a bottom, a propeller in'said tank on a shaft passing through a side wall of said tank near the junction of the bottom and such side wall, the side walls being in clined away and thebottom being inclined downwardly from said propeller, such Walls and bottom adapted to deflect. liquid hurled radially from said propeller thereagainst toward the portion of the Walls of the tank opposite the propeller, the walls opposite thepropeller being inclined back toward the propeller and adapted to cause liquid driven thereagainst by the propeller to return to the propeller.

bottom Wall,

2. In a device of the class described, the

combination of a tank having closed side .walls and a bottom, portions of said side walls being inclined away from a position adjacent the junctureof such side wall portions and the bottom, the bottom being inclined downwardly from such position when the tank is vertically arranged, and means atsuch position for hurling the liquid contents of the tank in a vertical or substantially vertical plane against inclined portions of such Walls and said downwardly inclined portion of the bottom of the tank, and for driving contents of the tank against the portions of the walls opposite said means, which opposigte side wall portions are inclined to deflect -he liquid back tdward said means. 1

3. In\ allevice of the class described, the.

combin' tio f a tank having side walls and a bott i iortions of said side walls being inclined away from a, position adjacent the juncture of such side wall portions and the the bottom being inclined downwardly from such position when the tank is scjtn ertically, a second portion of the bottom wall of the tank inclined upwardly toward the portions of site said position, and

the side Walls oppoa propeller having blades substantially straight radially located at such position for hurling the liquid contents of the tank in a vertical or substantially vertical plane against such inclined portions of such Walls and bottom of the tank, and for driving contents of said contents of the tank tank against the portions of the side Walls opposite said position and said second portion of the bottom Wall. j

4. In a device ofthe class described, the combination of a saucer-shaped bottom, a rotatable propeller shaft projecting through a side wall adja cent the bottom, a propeller mounted on said shaft close to the side wall and adapted when rotated to hurl liquid against curved portions of the tanks side and bottom Walls adjacent the propeller, and to project othercylindrical tank having a means through which through which a propeller shaft extends into said tank and terminates therein, said openng being nearthejunctlon of the bottom and sidetank located near the junction of the bottom and side walls thereof, the side walls and bottom being inclined away from said propeller and adapted to deflect liquid hurled radially from said propeller thereagainst toward the portion of the walls of the tank'opposite the propeller, the walls opposite the. propeller being inclined back toward the propellcr' and adapted to cause liquid driven,

thereagainst by the propeller to return to wall of the tank, a propeller on said shaft and adjacent the end thereof in said the propeller, said propeller being located I so low in-said' tank as to remain submerged as long' as an appreciable amount of liquid remains therein, the blades of the being substantially straight radially, a pulley or like device on the otherend of the shaft through which the same is driven.

In a device of the class described, the

combination of a tank having side Walls and a bottom wall, portions of said side walls being inclined away from a position adjacent the junction of such-side wall portions and the bottom wall, a propeller at such position for hurling'the liquid contents of the tank propeller 1n a vertical or-substantially vertical plane against such inclined portions of such side walls and a bottom inclined upwardly opposald propeller driving against the portions of site said propeller,

said side walls opposite'the propeller and against the upwardly inclined bottom whence it is deflected upwardly against the side walls of thetank.

In witness whereof, I have hereunto iil finred my name'this 24th day of December,
